I have to agree here.  I think a daemon is a heavy handed solution
and there isn't any good way to know how long temp files should
live.

Perhaps a variant on G_tempfile(), that works like tmpfile(), for
those cases where the name doesn't need to get passed around, and
once created, the file is kept open until no longer needed.

FILE *
G_tempfile2()
{
   char *name = G_tempfile();
   FILE *tmp  = fopen (name, "wb+");
   unlink (name);
   return tmp;
}

(course, a little error checking is needed...)
